Vivek,
This is the kind of question that if you have to ask you are not ready for
the answer. The best advice I could give you is to read Nitin Vengurlekar's
"ASM Best Practices" white paper and refer you to Oracle's Cluster Ready
ServicesInstallation Guide. If you've never done this before you should
brace yourself for some heavy reading.
In short to answer your questions the raw devices (LUN's) you want to use
for ASM must be shared and visible to all nodes. This is generally done
using HBA (host bus adapter) cards that allow your servers to "see and
interact with" the SAN storage array. There are some specifics in
configuring ASM on Solaris (which slices you can/should use) and which slice
to never use. Regarding commands for SAME. This is done by having your
storage administrator stripe the volumes across several physical devices.
Then you as the DBA come through and configure your ASM volume groups as a
combination of these "striped" LUN's. In other words the LUNS are striped on
the SAN and the ASM Diskgroups provide a second layer of striping.

Subject: Creation of ASM Disk Group on Solaris 10 ?
Folks
Need to Setup a 2 Instance ASM-RAC Database from scratch for an internal
Test Benchmark.
* What Commands are used to create an External ASM Disk Group on
Solaris 10?
* Any Additional Solaris Commands to make the SAME Disk Group Visible
to BOTH SUN Nodes?
NOTE - Disk Group to use External Hardware RAID (10) provided by the Storage
Box
Oracle 10gR2 on Solaris 10
Any Docs, Links will help
Cheers & Thanks indeed
Vivek
